Title: Improvements in and relating to inertia switches
IPC: H01H35/14
Filed: 1945-04-14
Abstract: 590,144. Inertia switches; switches held set and freed mechanically. BIRD, F. W. R. April 14, 1945, No. 9373. [Class 38 (v)] An inertia switch for mounting in an aircraft &c. is actuated by movement in one direction only of a resiliently restrained steel ball 16. The ball 16 is enclosed between the side covers of a casing 10 and is trapped against the casing 10 and a hardened steel plate 45 therein by a spring-loaded plunger 17 and a stud 19 or a pivoted detent 21. When the aircraft is subjected to a severe deceleration, e.g., in excess of 2¢g., the ball 16 moves the plunger 17 and allows the detent 21 to release a striker 23, an insulated striker pin 25 then closing contacts 27, 28. To recock the switch, the striker 23 is retracted by withdrawing a knob 31 actuating a catch 29, while the ball 16 is held free of the detent 21 by inserting a key 52 through a hole 46. A pointed projection 44 of the striker 23 provides a visible and tactile indication of the switch position. A pin 33 may be inserted through a hole 46<1>' in the casing to hold the catch 29 when the latter is withdrawn, thereby locking the striker 23 inoperative. Spring-biassed pivoted plates 47, 47<1> cover the holes 46, 46<1>. The plunger 17 moves in a cylinder 18 forming an air dash-pot, with a bleed hole 53, the loading of spring 41 being adjustable by a screw 42 which may then be locked by centre-popping and sealing compound. The screw 42 becomes inaccessible when the casing is mounted by lugs 11. The side covers may be of suitable transparent material and - pegs may be inserted in the base to prevent the ball from rolling out when the side covers are removed. Internal leads from the contacts 27, 28 terminate in a box 40.

Patent GB-985497-A (GB)
Title: Process for stabilising ketonic compounds
IPC: C07C45/78
Filed: 1962-03-12
Abstract: Normally liquid aliphatic ketones are stabilized against changes in colour and/or odour by treatment with gaseous hydrogen at 70 DEG  to 200 DEG  F. and 40 to 250 p.s.i.g. in the presence of a hydrogenation catalyst, the duration of hydrogenation being such that no substantial conversion of the ketones occurs, and are stored either as the resulting mixture of ketone and catalyst or after separation of the catalyst.  Any known hydrogenation catalyst may be used but preferred catalysts are the nickel catalysts, e.g. nickel-chromium and nickel-molybdenum alloys and, especially, Raney nickel.  The preferred reaction time is 5 to 120 minutes.  The hydrogenation may be performed batchwise, intermittently or continuously, in which case it is advantageous to employ a stationary catalyst bed and 50 to 100 p.s.i.g. for 5 to 40 minutes. Inert solvents may be used but it is generally preferred to effect the hydrogenation with the liquid ketone alone.  In the examples, methylethyl ketone, diacetone alcohol and mesityl oxide are stabilized by hydrogenation in the presence of a Raney nickel catalyst.

Abstract: 169,738. Whitehead, M., and Scott, E. April 7, 1920. Fats and fatty oils, extracting by solvents. In a counter-current process for the extraction of oils &c. from crushed seed or other vegetable matter by means of volatile solvent and in which solvent is expressed from the mass after each immersion, the meal from a pipe a is conveyed through a jacketed conduit b and falls on to a preferably inclined screen h<1> in a tank g<1> so that its progress is retarded while it mixes with used solvent from pipe j<1>. The meal is then conveyed to wring- ing-rollers t<1> through a conduit m<1> having its bottom perforated from above the level of the pipe j<1> so that drained or expressed solvent runs down an outer conduit q<1> to the tank g<1> but below the screen h<1>. The pressed meal falls down a conduit f<2> and is passed through a series of similar tanks, conduits, and rollers to a perforated conduit x in which it is freed from solvent by steam or vapour from a pipe 5<a> in the lower half of a divided jacket 4, the vapours being drawn off to a condenser through pipes 5. Pure solvent is fed from the tank v to the last tank g<4> by a valve u and pipe j<4> and through the series by pipes k<4> and j<1> to the last outlet pipe k<1>, which leads to a solvent-recovery apparatus. The recovered solvent is returned to the tank v by a pipe w. Solvent vapour in the tank g<1> or pipe f<1> is drawn to the recovery apparatus through pipe e.
